Application filed December 4, 1912. 7 Serial No. 734,881.

To all whom it may concern:

Be it known that 1, JOHN Osnonnn, a citizen of the United States,residing at Hotelikiss, county of Delta, and State of Colorado, iaveinvented certain new and useful Improvements in Hose-Swivels; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in swivel joints for hose, myobject being to provide a construction whereby a hose line, as a gardenhose, spraying hose or fire hose, may be provided with joints atsuitable intei sis, of such construction that one member of the joint,or the member connected with one hose section, may turn freely withinthe member connected. with the other hose section, to prevent thebending or kinking of the hose in such a manner as to interrupt the freeflow of fluid therethrough.

My improved construction is also equally applicable to hose for carryingfluids of all kinds, as air, or motive fluid for pneumatic tools of alldescriptions.

Having briefly outlined my improved constructi on, I will proceed todescribe the same in de ail. reference being made to the accompanyingdrawing, in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is an elevation of a hose pipe connected bymeans of a swivel joint of my improved construction. Fig. 2 is a centrallongitudinal section of the same. Fig. 3 is a view partly in sectionillustrating the joint members, but not assembled in operative relation.

The same reference characters indicate the same parts in all the views.

Let the numerals 5 and 6 designate the two sections of hose pipe to beconnected by my improved joint. which may be designated in its entiretyby the numeral 7. This joint includes members 8, 9, 10 and 12. Themember 8 consists of a sleeve threaded at both extremities, as shown at1.5 and 16, and having an interiorly projecting, centrally locatedcollar 17 which engages the member 9, the latter consisting of a tubularstem which passes axially through the sleeve 8 and is provided at oneextremity with an enlargement or head 18 which fits the bore of thesleeve, the said head forming a chamber around the stem 9 and betweenthe collar 17 and the head, in which is located a packing 19 to form afluid-tight joint. In the oppos1te extremity of the sleeve is inserted agland 20 forming a chamber between itself and the collar 17, in which apacking 21 is located. This construction is of the stallingbox type. Thegland is secured in place by the interiorly threaded cap 12, which isscrewed upon the exterior screw threads 15 of the sleeve 8. Theperforation in this cap fits the stem 9. The member 10 of the cou plingconstitutes a cap which is screwed upon the threads 16 of the member 8,the said member 10 having a reduced extension which enters the hose pipemember 5 and 15 secured thereto in the usual, or any suitable manner.The hollow stem 9 has an extension :24 which projects beyond the sleeve8 and enters the hose pipe section 6, its extremity beingcircumferentially toothed or roughened, as shown at 25, to facilitatethe forming of a proper connection with the hose pipe member. Anysuitable means, however, may be applied exteriorly to the hose sectionfor the purpose of securely connecting the latter to the hollow stem.

From the foregoing description it must be understood that the portion ofthe hollow stem which passes through the sleeve 8 and the cap 12 isadapted to rotate therein, thus making it practicable for one section ofthe hose pipe to turn freely with reference to the other section, whileat the same time the coupling connection, or joint, is fiuidtight.

Having thus described my invention, what I claim is:

A swivel joint for hose pipe comprising two members respectively securedto the two sections of hose, the first member consisting of a relativelylong hollow stem, while the second member consists of a screw-cap havinga hollow stem extension,- a sleeve having an interiorly projectingcollar midway its extremities and exteriorly threaded upon both sides ofsaid collar, said sleeve surrounding the first member and threaded intothe second member, the first member having a head at one extremity ofthe sleeve, a gland at the opposite extremity of the sleeve, the latterhaving an interiorly projecting collar opposite the exterior collarforming packing chambers between the head of the first memher and thegland, packing located in said chambers and a screw-cap surrounding theIn testimony whereof I ufiix my signature first mernlier alnd dthreadiedon the sleeve for in presence of two Witnesses.
